Taq 2X MeanGreen Master Mix contains loading dyes (blue ~4kb and yellow <25bp) that make monitoring process during electrophoresis easy, and a density agent that allows reactions to be loaded directly onto agarose gels. These dyes do not obscure visualization of reactions, as the bands run outside most products. This product has been optimized to allow prolonged use and storage at Ambient Temperature (15° to 25°C) and in standard Refrigeration (4°C).
